Griffin has a patented filtring technology for fuel. MICROBLOC® filters, at the same time, solid particles down to 2 microns and water that could appear in the fuel. Double function in the same filter.
Griffin Group is a global provider of products and services for the filtration industry, utilizing proprietary technology developed from over 30 years of professional experience purifying petroleum-contaminated seawater. In 2003, Griffin scientists developed MICROBLOC®, a revolutionary filtration technology, that is used exclusively in Griffin filtration systems. MICROBLOC® Multigrade Filtration Media Elements have tested to be 99.8% effective in separating water from diesel and bio-diesel fuels and can remove solid contaminants as small as 2 microns in size.
MICROBLOC®: The Clear Advantage
- Separate Water From Fuel At 99.8% Efficiency
Water can cause injector nozzle and fuel pump corrosion, ending in equipment failure and downtime. Unfortunately, water vapor continuously condenses inside your fuel tank. Griffin Fuel Filter / Water Separators eliminate this worry by removing water and other contaminants from your fuel supply. All Griffin Fuel Filter / Water Separators use the same MICROBLOC® Multigrade Filtration Media technology. In moisture content tests conducted by PSB Corporation, Singapore on fuel samples taken from a fuel filter / water separator employing MICROBLOC® Multigrade Media, 99.8% effectiveness of water removal was found to be achieved after 30 minutes of operation of the fuel filter / water.
- Remove Damaging Contaminants
Even small, nearly invisible particles can damage injectors and pumps, reducing fuel efficiency, robbing power, or worse. Each refuelling adds millions of tiny contaminants to your fuel system. MICROBLOC® filters protect your engine from solid contaminants by filtering particles down to 2 microns in size. Elements are available in 2, 10, and 30 micron ratings.
- High Capacity
MICROBLOC® elements provide multi-layered filtration. Corrugated filtration media means more surface area to trap contaminants.
- Longer Filter Life
MICROBLOC elements don’t need replacement as often as “will-fit” filter cartridges. MICROBLOC® filtration efficiency is up to 10 times greater than conventional media.
- Built to Last
Griffin Fuel Filter / Water Separators are built to take on any filtration job.
- Easy To Replace
All MICROBLOC® replacement elements meet or exceed OEM specifications and are easy to replace without the use of special tools.
- Enhance Engine Power
Griffin Fuel Filter / Water Separators enhance engine performance and reliability. You will feel your engine is more powerful and smoother after you install Griffin filters. Griffin filters will give your engine longer life.
- Reduce Fuel Consumption
A cleaner running engine runs more efficiently, and uses less fuel.
- Environment Friendly
Clean Fuel means cleaner exhaust. Griffin Filters reduce exhaust pollution more effectively than other similar products.
- Best Performing, Most Cost-Effective Choice
Griffin Fuel Filter / Water Separators are the right choice for fuel filtration. Relying on research, science, and technology, rather than marketing hype, Griffin can offer products that meet and exceed the leading brands at a competitive prices. Griffin filtration systems with MICROBLOC® are simply the best performing and most cost-effective choice for your filtration needs.
How it works?
Four Stage Filtration Process:
GRIFFIN filters remove contaminants and separate water using a four stage process.
- CENTRIFUGAL STAGE:
Larger solid contaminants and free water are separated.
2. COALESCING STAGE:
Smaller water droplets and solid contaminants are filtered out by MICROBLOC® multigrade filtration media, causing them to coalesce together and fall into the collection bowl.
3. MICRO ACTION I STAGE:
Micro action filtration removes the smallest water droplets and solid contaminants from fuel.
4. MICRO ACTION II STAGE:
A second micro action filtration ensures nearly 100% pure fuel filtration.
In gasoline engines it is mandatory to install a filter according to international regulations, which is more restrictive with diesel fuel engines. In these last ones, the function of the filter is double, on one hand it must prevent the access of solid particles to the engine and, on another hand, it should avoid that the water passes to the combustion chamber. This dual function is developed by the water and fuel separator filter.
What is it?
A water separator filter is a diesel engine and injectors protection system. This device is not exclusive to recreational boats and commercials ships, but is also installed in large motor vehicles of road vehicles.
How does it work?
The filter has several parts, depending on whether it fulfills the dual function of filtering the solid particles or only decants the water contained in the fuel. Usually the same device runs both tasks. Thus a filter of paper or similar material with a minimum porosity is different to capture the solid particles that barely measure a few microns and a second chamber where the water separates.
The process by which the fuel is separated from the water differs according to the manufacturer. Some choose to subject the liquid to centrifugal pressure and others are based on decantation. Whatever is achieved is that the water, denser than the fuel, is placed on a lower bowl (opaque or transparent) where you can drain the liquid through a key.
The probability of water in the fuel is actually minimal, but it can be caused by contamination during transport, storage in port or in the tanks of the ship itself due to condensation.

The bilge pump is one of the most important safety elements on board. The mission is not only to keep the bilge area free of water, also the boat dry. Avoiding also the bad odors coming from standing waters.
The number of pumps and the flow needed is determined by the length of the boat and the size of the different separated areas around. At bow, center, engine room, showers, holding tanks... places where a bilge pump in perfect condition is required in order to avoid non-welcome risks.
The correct situation of the pumps is the first step for proper operation. There are submersible and remote mounting pumps. Non-submersibles have impellers with an easy replacement in case of breakage or wear. We have to put them out of any contact with liquid, even with the heel of the boat.
It is also important to have a drawing with the pumps situation for the crew to find them easily when revised.
Each pump should have a power and flow rate adjusted to the needs of the ship. If we check power drop in a bomb, before replacing review the installation if there is any elbow, blocked or another reason that makes the pump does not work properly.
The water inlet must be protected by a strainer to prevent the entry of solids that clog the pump or even break the internal turbine. We will have to check state and no elements that clogged. No matter how good the pump is, it will not work properly with poor suction.
If we notice engine overheating, can be by a malfunction, continuous use higher than specified by the manufacturer or poor contact between electrical devices such as bearings and brushes.
There are some accessories for pumps such as magneto-thermal and vacuum switches in addition to alarms and signal panels. Vacuum switches allow the pump to be always wet and in the best conditions, preventing breakage of membranes and warm in the absence of refrigeration. We must be careful not to leave it plugged at the harbour because is forbidden pouring liquids such as oils and fuels, present in the bilge.
The turbine is the most important part inside the pump because it is responsible for aspirate and expel the liquid with its rotation. If submersible pumps broke, we must replace the entire pump. The remote mounting have rubber impellers which are more effective and also enable replacement.
